| Description |
|
The range deleter batch size default value changed from 128 in MongoDB 4.2 to 1000 in MongoDB 4.4. This increased batch size speeds up overall range deletion. However it has led to a large number of chunk migrations failing. As a short-term fix, we would like to return to the 4.2 behavior by defaulting the rangeDeleterBatchSize value to 128.
